Concrete, described internal layer and outer concrete formula following (in mass fraction):
Ethylenic copolymer layer is with low cost ethylenic copolymer, functional filler, linking agent and oxidation inhibitor composition, ethylenic copolymer is ethylene-butene copolymer (POE5061 of Exxon Mobil company), inorganic filler is titanium dioxide, linking agent is the peroxidation 2 ethyl hexanoic acid tert-butyl ester (A Kema chemical company), oxidation inhibitor is 2,2 '-methylene radical-bis--(4-methyl-6-tert butyl) phenol (Nantong Xin Chang Chemical Co., Ltd.), this layer thickness is 0.2mm.Concrete formula is as follows:
This double-deck photovoltaic component encapsulating glued membrane adopts the method for double-deck curtain coating co-extrusion to make.
Double-deck solar cell glued membrane described in the utility model, is applicable to photovoltaic module cell piece back side encapsulation or has the BIPV component package of shading characteristic requirement.It neither can affect the generated output of photovoltaic module, can solve again the demands such as the height reflection, heat conduction, opacifying property of cell piece back side glued membrane.
The foregoing is only embodiment of the present utility model; but protection domain of the present utility model is not limited to this; any those of ordinary skill in the art are in the disclosed technical scope of the utility model; the variation that can expect without creative work or replacement, within all should being encompassed in protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with the protection domain that claims were limited.
